|go ahead... be a heretic|
I have similar concerns regarding Point 1 that others have raised.
If a specific user posted many "offensive" posts in a single thread, downvoting these should be acceptable; subsequently downvoting many posts by the same user in other threads (perhaps as a form of punishment) should be unacceptable.
If you downvote many nodes, you eventually get "dog votes" messages in the XP Nodelet. Would it be possible to also have something similar (perhaps with "policy violation" messages) for Point 1 infringements?
You've addressed "massive downvoting"; what about "massive upvoting"? Giving all votes to a single user (perhaps to help out a friend) is probably also an abuse of the voting system.
I agree with Points 2 & 3 — no issues there.
The "Any violation of this policy ..." statement comes across as dictatorial. I'd suggest toning this down: s/will result/may result/ would be a good start. I see "way down in the thread" you've moderated this with "Also, we would not take any action without first discussing it with the monk." — I think that should be part of the policy, not hidden away in a side note.
